Pew Internet & American Life Project published a new report (pdf) called “Teens, Privacy and Online Social Networks: How teens manage their online identities and personal information in the age of MySpace”. The report talks about what kind of information teens share on social networks and what they keep hidden from strangers (and/or parents).
